Some 1985-86 S/T Jimmys/Blazers equipped with TBI engines may experience a stumble or hesitation while making a turn. This condition usually occurs when the truck has less than 1/8 of a tank of fuel. This condition may be caused by fuel "sloshing" away from the fuel pickup during a turn.
If this condition is encountered, it can be corrected by installing a new fuel tank that has a built-in reservoir that prevents the fuel from "sloshing" away from the fuel pickup during turns.
